Well if your country is drowning in a wave of religious conservatism, it is going to be full scale holy war if Hatikvah is played As the in effect de facto rule here, if you managed to get the papers and not get rejected despite fulfilling them, you have to compete without any hint of Israel.
I watched how complicated the whole process of Misha Zilberman trying to qualify to Rio 2016 in Badminton World Championships 2015. After a dramatic arrival (both sides blaming each other for making controversy), hardliner group members are ready to attack. The security used stalling tactics. Then the organizers inside switched his court to the one near the exit. One of the hardliner group member enters the arena, watching the original court empty without realizing Misha is playing at the other court. Then it was like "See? No Jews play here. Now get out".
